Four people were arrested in connection to three separate marijuana-related searches in the Mount Shasta area.

Three people were arrested after members of the Siskiyou Interagency Marijuana Investigation Team, or SIMIT, searched a home in the 200 block of Cricket Road in Mount Shasta on Friday.

The home included a honey oil lab and sophisticated THC extraction equipment valued at more than $400,000, according to the Siskiyou County Sheriff's Office.

The equipment, along with about 19 pounds of marijuana processed into various forms, was seized during the search. Also seized was 449 ounces of concentrated cannabis and 116 electronic cigarette cartridges, sheriff's officials said.

Three people were arrested on suspicion of manufacturing a controlled substance. The suspects were not identified by the sheriff's office.

The SIMIT team also searched two other properties in Mount Shasta Vista's Juniper Terrace area, seizing 337 marijuana plants. Two loaded firearms were also located during the search.

Officers arrested one person during the Juniper Terrace search. The person arrested was not identified by the sheriff's office.

Officials with the Siskiyou County Planning Department also went along on the searches, "and various county ordinance violations were detected and nuisance abatement processes initiated," sheriff's officials said.

Growing marijuana for personal use in unincorporated areas of Siskiyou County is limited to 12 plants grown indoors in an approved structure, sheriff's officials said.
